Question

The value of the expression x3 + y3 , when x = 2 and y = -2 is​

Answer 1

Given: The equation is$x^3+y^3$ and$x=2, y=-2$.

We have to find the value of the above expression.

As we know that the value of the$x\ and\ y$ is given so by putting these values in the above equation we are solving the above equation.

We are solving in the following way:

We have,

The equation is$x^3+y^3$ and$x=2, y=-2$.

$=>2^3+(-2)^3\\=>2\times2\times2+(-2\times-2\times-2)\\=>8+(-8)\\=>8-8\\=>0$

Hence, the value of the expression$x^3+y^3$ is$0$.
